DRIVE LINE
Torque flow diagram when driving in a straight line equal grip on
both driven wheels.
Torque flow diagram when turning to the left or when grip differ-
ence between the left and right driven wheels.
Multi-disc brakes are mounted at the left
and right on the side gears, and react to
relative movement between them and
the differential cage by generating a
braking force dependent on torque. This
braking movement has the effect of par-
tially locking the output side concerned,
and increasing the torque on the side
with good wheel grip. The braking mo-
ment in other words, acts as a substitute
for the torque reaction on the side with
poor grip.
To avoid wheel spin, the two differentials each have a differential
brake with a locking value of 45%. When the differential brake is
activated, the drive wheel is forced to roll at the rotation speed
decided by the locking value.
